Review of structures for the cottages, which can be constructed as a geodesic dome

Structures in the country, carried out in a non-standardshape, decorate the site and increase its attractiveness. Houses, gazebos, greenhouses, constructed in the form of geodesic domes, certainly will not go unnoticed. Implement the project small geokupola a snap. With the construction of such facilities able to cope for many gardeners, despite the originality of the frame structure. The minimal cost of the acquisition of building materials allow to perform all the work in the shortest possible time. Dome technology interest and suburban housing builders. The space inside this cottage has high functionality. The house-dome is 20% more usable space by reducing the number of frame structures. In this and manages to save building materials.


Architectural structures, as the carrierdesign which used the retina, appeared in the middle of the last century. The first geodesic dome designed by Richard Fuller (USA). His American invention patented. Unusual for the time construction was planned to erect in order to obtain cheaper luxury housing in the short term. However, it failed to achieve mass building techniques of the invention.

The extravagant project has found application infuturistic building include a café, stadiums, swimming pools. Notice the geokupola and landscape designers to the data structures of steel placed in the center of landscape composition. And then, and now attracts professionals roominess of dome structures. Use your imagination and fantasy, you can find a variety of options for use of the space inside the sphere.

geodesic dome design is differenthigh load-bearing capacity. From the value of the diameter of the spherical frame depends on the value of the entire construction area. Small five-meter height of the dome built without a construction crane by two or three people.

Why is this design better than others?

The spherical shape helps geokupolaharmonization of the space, which is saturated with positive energy. Being in a spacious and incredibly cozy round room is good for health. No wonder the dome structure referred to the environmental facilities. The advantages of light geodesic structures include:

  • no need to device a thorough foundation, which greatly simplifies and speeds up the installation of the facility;
  • no need for construction machinery, which reduces noise at times during the work.

The basis of the construction is geokupolov frame-panel technology, allows you to quickly build on a country or suburban area a number of structures for various purposes, such as:

  • bath or sauna;
  • house or summer kitchen;
  • garage or carport;
  • gazebo or play house;
  • pool year-round use;
  • a greenhouse or a greenhouse, etc.

The main types of geodesic structures

Construction geokupolov differfrequency decomposition of the sphere surface into triangles. The frequency partition is usually denoted by the letter V. The number standing next to the V, shows a number of different structural elements (edges) that are used to build the frame. The greater the number of edges is used, the stronger it turns geokupol.

There are six types of geokupolov of which are actively used in the construction of only five:

  • 2V dome (height of the building is half a sphere);
  • 3V dome (height of the building is equal to 5/8 of the sphere);
  • 4V cupola (height of the building is half a sphere);
  • 5V cupola (height of the building is equal to 5/8 of the sphere);
  • 6V cupola (height of the building is equal to half of the sphere).

It is easy to notice that the hemispherical shape of the object can be achieved only at an even frequency partition.

frame scheme of the geodesic dome type 2V

Driving frame geodesic dome type 2V to create small structures. Different in the length of the edges are highlighted and marked with letters

For small dachas usually chosen2V dome design. Frame collect two types of edges, denoted in the diagrams for the convenience of Latin letters A and B, as well as provide additional blue and red. Preparations are also color marked to simplify the process of assembling the frame structure. To connect the individual edges frame geodesic dome used special nodes called connectors. Three types of connectors are used when installing 2V-dome design:

  • 4 final;
  • 5 end;
  • 6 final.

To calculate the length of the ribs and the number of connectors used online calculators, in which block data source object: a base radius, split frequency, the desired height of the dome.

Three types of connectors

Three types of connectors used to connect the dome frame edges converging in a single point (polygon)

Large objects hemispherical diameterthe base of which exceeds 14 meters, built with the help of 3V and 4V domes. At a lower frequency partitions are too long edges, making them difficult to harvest and installation. During the construction of the dome 3V ribs length is almost three meters. Collect the framework of such lengthy materials is problematic.

By selecting a different type of a dome (4V), reduce the lengthribs to 2.27 meters, which greatly simplifies the assembly of the dome structure. Reducing the length of the structural elements leads to an increase in their number. If 3V dome with a height 5/8 sphere 165 has ribs and connector 61, the dome at 6V at the same height as the ribs 555 has pieces and connectors - 196.

Pile foundation for the installation of large domed structures

Pile foundation for the installation of large dome design allows for the construction of the necessary strength and stability

An example of the construction of the dome greenhouses

Before the construction of determinedfootprint future greenhouse, as well as its height. The value depends on the square base circle radius, which fits around and is described by a regular polygon. If we assume that the radius of the base will be equal to 3 meters, and the height of one and a half meters of the hemisphere, for the assembly 2V dome will need:

  • Ribs 35, which is the linear dimension of 0.93 m;
  • 30 ribs length 0.82 m;
  • 6 five-pointed connectors;
  • 10, four-connector;
  • 10 six-pointed connectors.

selection of materials

As the frame ribs can be usedbars, fence board, shaped tubes, as well as special dual stand-brace. When harvesting fins allow for their width. If selected fence board, it is necessary to saw into equal parts using a jigsaw.

Align site

Having prepared all the constructive elements of the futuredome, start leveling the place for the construction of buildings. It is necessary to equip the building level, as the area must be perfectly flat. Lined place slept gravel layer that properly compacted.

The construction of the base and frame assembly of the dome

Then proceed to the base constructiongreenhouses, the height of which, together with the height of the dome make the room comfortable for the operation. After the founding of the construction, start to collect the frame of the ribs on the scheme, which shows the sequence of connections. As a result, should get a polyhedron.

Frame polutorametrovoy hemisphere everything for greenhouses in the country

Frame polutorametrovoy hemisphere everything for greenhouses in the country is made of wooden bars, connected by way of a connector on the circuit with each other

To facilitate the assembly can be achieved by various stainingalong the length of the ribs in different colors. Such color highlighting individual design elements to avoid confusion. Isosceles triangle, collected from bars or pieces of shaped tube, fastened to each other connectors (special provisions). Although small design manages to fasten screws and standard mounting tape.

Attaching polycarbonate sheets

To frame bolted polycarbonate sheets,a cut in the shape of triangles. When installing using special screws. The seams between adjacent sheets of polycarbonate decorate and at the same time and insulated, rails.

Construction of interior space

According to the greenhouse perimeter make the beds, and theirheight should be equal to the height of the base frame. When fencing decoration using various materials. Better and elegance are combined with plants grown in a greenhouse, natural stone. For the convenience of the track in the greenhouse if possible make wide. Be sure to equip the place for relaxation, from which you can admire the beauty of the strange plants and flowers.

The dome greenhouse, covered with polycarbonate

The frame of the dome greenhouse made of shaped tube. The faces of a polygon made of polycarbonate sheets, light-transmitting ultraviolet rays and delay

For the rational use of the internalspace use polypropylene tubes that attach to the frame edges. These tubes are hung pots with ample plants. Along the edges of the greenhouse are planted low-growing plants, and closer to the center - tall. To keep the inside of the dome a sufficient level of humidity set in the northern part of the construction of a water tank. Enhance the greenhouse effect inside the greenhouse allows the reflective film, which is attached to the frame structure located above the tank with water.

The internal arrangement of the dome greenhouses

The internal arrangement of the dome greenhouse is carried out with maximum use of available space. Plant height influences the choice of the place of their planting in the greenhouse so unusual shape

Gazebo in the form of a semi-open hemisphere

Garden furniture, made in the form of a semi-openhemisphere, will be the most attractive place in the summer cottage. Going this air facility within one working day. Mounting frame made of shaped tube. The diameter of the dome at the same time should be 6 meters and the object height - 2.5 meters. At such sizes can be obtained 28 square meters of usable space, large enough to accommodate friends and relatives. Calculation of structural elements 3V dome is also done with the help of online calculators. As a result, the automatic counting it turns out that you will need for the construction of the gazebo:

  • 30 pieces of ribs for 107.5 cm;
  • 40 pieces of ribs 124 cm;
  • 50 pieces of ribs 126.7 cm.

The ends of the ribs, a cut of profile pipes,flattened, drilled and bent at 11 degrees. For convenience, the lattice geokupola assembly scheme is marked by the same length of the ribs of the same color. That will have three groups of elements, which are fastened to each other according to the diagram with washers, nuts and bolts. After completing the installation of the frame, producing flooring covering material, for which you will find:

  • plywood sheets;
  • colored polycarbonate web;
  • battens;
  • soft shingles and others.

If only the upper part to close the frame, theGet the original semi-outdoor gazebo. With the curtains you can decorate the remaining free space on the sides of the gazebo. To achieve extraordinary design dome structures allow your imagination.

Collapsible metal frame can beIt dismantled at any time. If you want to design flat packed transported in the country, where he quickly assembled and served a cover made of fabric vlagoottalkivayuschey.

And maybe build a house?

House, unlike the above constructions,It needs a device melkozaglublennogo insulated wooden base. On the construction of the foundation are fixed corner posts foundation walls, as well as horizontal struts. After embarking on the installation batten dome.

The spherical surface of the carcass on the outsidesutured plywood sheets with a thickness must be at least 18 mm. In selected locations installed windows and doors. For warming designs use a new generation of thermal insulation materials on the inside and the cover sheet of plywood or other finishing material.

Construction of the country house in the form of geokupola

Construction of the country house in the form of a geodesic dome is carried out using a heat-insulating material, laid between the inner and outer trim double frame

For quick attachment of all materials recommended for use in the construction of a country house system of double struts.

As you can see, applied geodeticdome at their summer cottage can every gardener. If you own the original construct a building you can not afford, then hire a professional. Many builders are happy to take up such projects, because they can be built in a short time.
